added a comment - 11/Dec/08 13:40 When we had the problem before we were using Clover 1. This patch updates the build to use Clover 2, which has some differences to do with how the ant task is defined: http://confluence.atlassian.com/display/CLOVER/1.+QuickStart+Guide . You now need to specify a clover.home property for ant.
I tested with Clover 2.3.2 which is the version on Hudson, and it managed to instrument all the source (which is where it failed before), and run a test. I had to increase the memory available to ant to perform the instrumentation (see http://confluence.atlassian.com/pages/viewpage.action?pageId=79986966 ), using
export ANT_OPTS=-Xmx256m
I think we could try enabling this on Hudson again to see if it works.
